Woody Allen's romantic comedy "Annie Hall" (1977) was a cinema landmark for countless reasons, including its wry, absurdist script and Allen's long-suffering character, while perfectly capturing the sensibilities of New York and L.A. But it would not have worked without Keaton's scintillating, ditzy and touching performance as Annie.

While Keaton won raves for her comic turn in "Annie Hall," she also earned critical plaudits for her dramatic performance in "Looking for Mr. Goodbar" (here with Richard Gere), as a young woman self-destructively hitting the singles' bars.

After the very public disintegration of Woody Allen's relationship with Farrow, Keaton returned to the director's "Manhattan Murder Mystery" (1993). In the comical thriller about a couple of amateur sleuths investigating the mysterious disappearance of a neighbor, the two played as if Annie Hall and Alvy Singer were an "old married couple," with as much exuberance as their previous screen counterparts.
